如果你不需要它是一个整数，而是任何随机的唯一标识符，你可以使用newid()

SELECT table_name, newid() magic_number 
FROM information_schema.tables

您需要为每一行调用RAND()。这里有一个很好的例子

很简单:

DECLARE @rv FLOAT;
SELECT @rv = rand();

这将把一个0-99之间的随机数放入表中:

CREATE TABLE R
(
    Number int
)

DECLARE @rv FLOAT;
SELECT @rv = rand();

INSERT INTO dbo.R
(Number)
    values((@rv * 100));

SELECT * FROM R

如果你不需要它是一个整数，而是任何随机的唯一标识符，你可以使用newid()

SELECT table_name, newid() magic_number 
FROM information_schema.tables

如果你需要一个特定的随机数你可以使用递归CTE:

;WITH A AS (
        SELECT 1 X, RAND() R
    UNION ALL
        SELECT X + 1, RAND(R*100000) --Change the seed
        FROM A
        WHERE X < 1000 --How many random numbers you need
    )
SELECT
    X
    , RAND_BETWEEN_1_AND_14 = FLOOR(R * 14 + 1)
FROM A
OPTION (MAXRECURSION 0) --If you need more than 100 numbers

如果你想生成一个1到14之间的随机数。

SELECT CONVERT(int, RAND() * (14 - 1) + 1)

OR

SELECT ABS(CHECKSUM(NewId())) % (14 -1) + 1
